WS65909 Mitsubishi will not stay on.

Hello SD Tech, I wanted to ask if you would be able to repair the board if it was shipped to you. I am also having a problem with the Mitsubishi WS65909 - It will not remain on and prior to failure the television was experiencing problem with picture (it would shift - blurred images).

I am not permitted to do this by this site---I will give you any kind of information you need but cannot do what you ask----it sounds like a convergence problem plus--did you find instructions for this kind of repair? If you have asked me for information before I cannot tell who you are unless you reply to this solution.

Regards, SD TECH

Mitsubishi WS-A55 with a 2-3 error code


SD Tech - I have the error code 22 on my WS-A55. Power light comes on and then quickly shuts off. Looked at circuit board - there was greenish "gunk" on two of the electronic parts on the board in the center (behind the speaker grill) in the area labelled R5A62. Would you be so kind as to post repair instructions and the name of parts seller you mentioned above? Thanks!!!

I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR REPLACING THE STK-393-110 CHIP IN SETS THAT USE IT--available here for free if you need them. please let me have the info for my mitsubi. ws-7390


They are available but meant for the models that have that part on the middle board. There are a few models where chip is on a side board--instructions would still apply but you would have to do some things differently.

Mitsubishi 65 in Model 65909 DM Board replacement


There is not a replacement board available from Mitsubishi; you have two choices depending on problem: either a repair kit (widely available on the internet) or Contact PTS Electronics who will repair or rebuild it for you.

If you have questions let me know.

Main board malfunctioning where can I get a replacement part? left part number at work - believe it is 933B86600


The boards are no longer available from Mitsubishi, which board (signal, deflection, power) are you looking for?

A national company called PTS ELECTRONICS does repair some boards.

Let me know actual problem and I can advise.

My picture curves and colors are off and writing off


If it looks 3d with colors skewed you have a bad convergence IC.

The model indicated uses 2 of the STK-392-570 chips; they are located on the middle circuit board and a pair can be purchased on EBAY for about 14 dollars plus shipping.

I have repaired hundreds of these sets with this problem and I have composed and have available step by step, start to finish instructions for the do it yourself person who wants to repair this problem.

If you want the instructions (they tell you everything you will need and exactly how to do it) let me know here by using the "add a comment" button.

Please reply and understand total parts cost for this repair should be under 35 dollars total and the repair takes about one hour.

My 65 inch projection TV turns off within a few seconds when I turn it on. Why? No pictures or sound.


If power light does come on and a few seconds later it goes off---do the self check that the WS65909 MITSUBISHI should have:

On the front of the set press and hold both the MENU and INPUT(OR DEVICE) BOTH FOR 5 SECONDS AND THEN RELEASE BOTH BUTTONS.

Power light should blink a two digit code--error code---for example: 2 blinks, a pause and 2 blinks.

Let me know what code you get----it will repeat it several times---and I will tell you what it means.

WS-65511?

This model uses a single convergence IC chip----
STK-393-110.

The chip needs to be replaced and there are about a dozen light blue resistors in front of it that need to be checked also.

Considering you can buy the part on Ebay for about 12 dollars plus shipping---if you or someone you know can do it for you, you can save the set and a lot of money.

I have done hundreds of these repairs and I have had so many people here asking that I composed step by step-----start to finish instructions for this repair in this set----

The instructions tell you everything you will need to do the repair and are detailed.

I just today received a comment from someone who got the instructions tell me the repair went perfect and he now has a working TV again for a fraction of what a shop wanted to repair it.

If you want the instructions let me know, I am not allowed here to post MY email address, but you.....

Colors are seperated and arched


The WS-65809 uses two of the STK-392-570 convergence IC's---if convergence is skewed and will not adjust----both chips and any of the protect resistors around them that are bad need to be replaced.

The repair involves getting the middle circuit board out of the set---You can buy a pair of the chips on Ebay for less than 14 dollars plus shipping.

This all depends on if you are handy and know how to solder----each chip has about 18 pins that are soldered in-----I repaired one of these here yesterday for someone---repair takes about one hour.

If you are able to do it yourself you will save a lot of money as most shops charge 300-400 for this type of repair. If you get someone to do it for you make sure they change BOTH chips---

I have had so many people here ask me how do this repair that I have composed start to finish step by step instructions for this set---they tell you everything you will need to do the repair---if you decide you want the instructions let me know and I will post them here for you.

Not everyone can do the repair---

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW----I am here to help people.

Mitaubishi model ws65909


Sounds like a convergence failure. It needs the "ICs" or "S-T-K" packs replaced and realigned. I would recommend taking it to a repair shop.

Yes,but first it is necessary to repair the problem = replace
both STK392-570 IC's.............Then use remote to adjust
convergence............."inside the tv" is called servicer menu = adjust after repair is complete.You can expect to replace IC's
every five years or so.......................T.

PS Try to match your problem thread model # to actual model #
ie. VS-5043 does not match WS-65909........T.
